Oracle发布的去年今天大事记（oracle去年今天）
近日，Oracle发布了去年的大事记，回顾了这一年发生的各种大事。去年，Oracle放开了Java 13。Java 13是Java 13系列的第一个版本，可支持面向对象编程的扩展，例如参数化构造函数，并支持一些其他新功能和改进，如简化语法，多个switch原语，新的 JVM 引擎及改进的字符流操作等。
此外，Oracle还发布了Java 14。它主要实现了四个新特性：“逐字字符字面值”，“模式匹配”，“云中增强安全性”，以及“动态类文件 constant”。此外，它还可以改进内存管理，改进内存分配性能，改进常规功能（如 switch 的改进），改进字符流操作和其他改进。
还发布了对于Oracle Database 早期以及2019年发布的特性介绍和使用Oracle Database 19c。Oracle 19c提供了最新的数据库管理功能，允许开发人员更轻松地管理数据库资源和数据库应用程序，它还支持诸如Autonomous Transaction Processing（ATP）、Real Application Testing（RAT）和Multitenant Container Database（CDB）等常见功能。
此外，Oracle还发布了基于AI技术的云AI Platform，该平台支持AI场景的开发，例如语音识别，图像识别等。使用AI Platform，企业用户可以更轻松地利用人工智能解决各种问题，提高企业的效率。
去年，Oracle发布了新的开发工具，如Oracle Developer Studio 12.6，该工具专为开发人员提供了多种开发工具，如Java编辑器，可视化构建，调试和测试工具等，便于开发人员更轻松地构建和管理应用程序。
总的来说，去年，Oracle发布了多款新产品和工具，从而改变了计算机行业的发展走势。新的Java版本、Oracle Database大版本和AI Platform都极大地增强了企业的开发能力，同时也为开发人员带来了更多便利。

Recently, Oracle released the review of the major events that happened last year. Last year, Oracle open-sourced Java 13. Java 13 was the first version in the Java 13 series and it supports OOP extensions suchas parameterized constructors and also supports other new features and improvements suchas simplified syntax, multiple switch primitives, the new JVM engine and improved stream operations.
In addition, Oracle also released Java 14. It mainly implemented 4 new features: “literal, character by character”, “pattern matching”, “enhanced security in the cloud”, and “dynamic class file constant”. In addition, it can also improve memory management, improve memory allocation performance, improve general functions (such as enhancement for switch), improve stream operations and other improvements.
In addition, Oracle also released an introduction to the features released in the early Oracle Database and Oracle Database 19c released in 2019 and how to use Oracle Database 19c. Oracle 19c provides the latest database management capabilities that allow developers to more easily manage database resources and database applications and also supports common features such as Autonomous Transaction Processing (ATP), Real Application Testing (RAT) and Multitenant Container Database (CDB).
Also released is Oracle’s Cloud AI Platform based on AI technology, which supports the development of AI scenarios suchas voice recognition, image recognition and so on. Using AI Platform, enterprise users can more easily solve various problems with artificial intelligence and improve their efficiency.
Finally, Oracle released new development tools suchas Oracle Developer Studio 12.6 which provides developers with a variety of development tools suchas Java editors, visual builds, debugging and testing tools to make it easier for developers to build and manage applications.
In all, last year, Oracle released many new products and tools, which changed the development trend of computer industry. The new Java version, Oracle Database major version, and AI Platform all greatly enhanced the development capabilities of enterprises, and also brought more convenience to developers.
